ihavenoidea6 Posted June 30, 2006 Share Posted June 30, 2006 TI - 89 for the win =) I am also suspecting it is an exponential function rather than a polynomial Link to comment Share on other sites More sharing options...
LordSoultar Posted June 30, 2006 Share Posted June 30, 2006 Unfortunately, I don't have the $200.00 plus to buy Mathematica 8.0, and I am too lazy to right a sigma function in C++... Soultar, if you could release some code for that function, I think I could write a program for it for tip.it... EDIT: Is "floor" the same as calculating the minima of a curve? Sorry, I'm pretty good at math but not with terminology ;-) Floor is the same as INT, just means round down. I'll write up something in javascript now. Gimme a minute.

pedestrian01 Posted June 30, 2006 Share Posted June 30, 2006 Unfortunately the equation has been known for quite some time and tip.it already has the formula and a script to go a long with it. Though that is some nice math work. And although I'm stuck here with the TI-83+ I've used the TI-84 and am considering getting one soon. Link to comment Share on other sites More sharing options...
tefda Posted June 30, 2006 Share Posted June 30, 2006 Or: NO! You beat me to it! Bah humbug! Anyone could have gotten the formula if they just looked at the source code of any one of the experience calculators... or did a search for Experience Formula.

LordSoultar Posted June 30, 2006 Share Posted June 30, 2006 Here, plug this into a html document with a function call and it returns the exp needed for levels 2-99: Link to comment Share on other sites More sharing options...
lucasesco Posted June 30, 2006 Share Posted June 30, 2006 lol dude you messed up on calculations the answer is not correct. you need to replace the last 3 and find the quartic doozer number of the 7th digit to the right from the left. The you must find the square of all the uneven levels and divide it by zero. I SURVIVED THE 111 BUG If a turtle doesnt have a shell, is it naked or homeless ?

bigsword33 Posted June 30, 2006 Share Posted June 30, 2006 Also, just had a thought: What if I take Duke Freedom's research on the prices of rares and develop a regression algorithm for the prices of rares (i.e. inflation) THAT would be a pretty big acheivement. i'm sorry but you could only guess this. no equation can properly state the next price of an item, as in some realy life things. anything can happen, as in jagex taking away rares, some one quitting that is known to have thousands of rares, some one hording rares, or enough merchants banning together to make all rares go up in price. see? it wouldn't work right. but if you want to make an estimational equation, then go ahead. and it's would be pretty big, even then Link to comment Share on other sites More sharing options...
aqua_dragons Posted June 30, 2006 Share Posted June 30, 2006 ya, just a formula would not guess the prices of rares. Its called economics and it has plenty of formulas but nothing gets it right Link to comment Share on other sites More sharing options...
Esper_Jones Posted June 30, 2006 Share Posted June 30, 2006 Well, don't know if anyone stated this yet, but wrong. This is a close approximation, but it is not the actual formula. And the 84 sucks! ;) TI-89 Platinum all the way. Symbolic manipulation rocks. Jack of all trades, master of thieving. 259th to 99 thieving.

Death_By_Pod Posted June 30, 2006 Share Posted June 30, 2006 The Formula: X is level and Y is exp needed Y = 1.1240002159979X^4 - 169.81098284753X^3 + 8443.2450488426X^2 - 146185.46656323X + 586908.5427719 That quartic is never going to give you accurate data unless Jagex uses a quartic to determine XP/level. Its not going to be useful around the ends of the data (especially predicting levels >99). A better approximation would be a Lagrange Polynomial but you would probably need to use Matlab or some other mathematical program to solve it. But this is all silly when we know the exact formula.

Tomato Posted June 30, 2006 Share Posted June 30, 2006 Ok , here's the table: For my typing convenience, I will list exp values for every 5 levels over 100. Level: Exp needed: Rough Value 105: 18369700: 18.3m 110: 25216225: 25.2m 115: 33764557: 33.7m 120: 44266687: 44.2m 125: 56991468: 57m 130: 72224611: 72.2m 135: 90268688: 90.2m 140: 111443132: 111.4m --------------------------> OVER 100M EXP 145: 136084233: 136m 150: 164545144:164.5m I'm about 99% certain that the EXP requirements should double every 7 levels. That's the trend in the current available levels anyways... Link to comment Share on other sites More sharing options...
laws0074 Posted June 30, 2006 Share Posted June 30, 2006 I'm so glad someone posted the YEARS OLD formula. It's just sad when a high school student gets their hands on a graphing calculator and thinks that they actually know what they are doing. As far as predicting rares go that is something that can only be guessed and most likely would be guessed wrong. I will list just a few impossible to know variables that would need to be involved: change in new players change in old players leaving decreases in overall rares introduction of money removing skills introduction of money adding skills introduction of very rare highly sought after items people purposely influencing prices and so on and so . . .

Quasar889 Posted June 30, 2006 Author Share Posted June 30, 2006 Ok, I consider myself to be a math nut, but whoever could think of a Lagrange Polynomial certainly takes the prize from me. ;-) Could you perhaps enlighten me as to what exactly a Lagrange Polynomial is? I'll do a quick google to get some background info. Thanks in advanced... -Quasar889 You act like the game community is like the stinking bowels of hell.... In all reality.. its much.. much... worse.

Z_E_R_O_I_Q Posted June 30, 2006 Share Posted June 30, 2006 I'd like to put a caveat on this formula. It is rather inaccurate between the levels of 1-60. However, at level 60+, the exp is give or take 3% off. The intent of this function is to determine the amount of exp for levels above 99, so take this function with a grain of salt: it's not going to be 100% accurate... more like 88% accurate. So: Without further ado, The Formula: X is level and Y is exp needed Y = 1.1240002159979X^4 - 169.81098284753X^3 + 8443.2450488426X^2 - 146185.46656323X + 586908.5427719 Rather inaccurate? It gives 448998.106395 xp for level 1, couldn't possibly take that as a formula if it misses the right answer by 5400 times :?

sabster Posted June 30, 2006 Share Posted June 30, 2006 actually this isnt that hard. if you took alg 2.. maybe even alg 1 you should know how to do this. lol. all he did was put in the info into the lists.. went to graph. then did the function that follows the line with the slope and shows the rest of it. yawn. you just hit buttons.
